They were questioned over disorder-related offences after the game at St Andrew’s, which Blues won 2-1.

Two people were also taken to hospital with head injuries.

A large group of fans were “kettled” – contained by the police – outside the iconic Selfridges store in the city centre, as shown in pictures taken by Danny Gannon.

A large line of police vans also snaked down the street outside.

Match commander, Chief Supt James Andronov, said officers would review CCTV footage around the ground and in central Birmingham to identify suspected offenders.

“We had a strong police presence in and around the ground, and our officers escorted a large group of fans identified as being a potential disorder risk away from the ground to their transport,” he said.

“Other officers were placed at strategic locations to monitor the situation and deter trouble.”

Mr Andronov said the game was “comprehensively risk assessed” and defended the decision to allow both sets of supporters to leave St Andrew’s at the same time.

“Some people have questioned the decision to allow both sets of fans to leave the ground at the same time,” he said.

“It is rare these days to hold back supporters - it’s not been done at this fixture for several years as evidence suggests to do so often increases tension and the prospect of trouble.”

Anyone with information over disorder at the match should call police on 101.
